Automated Modal Identification Based on Improved Clustering Method

Figure 6

Clustering results by the (a, c, e) improved method and (b, d, f) previous method [16] for (a, b) setup 1, (c, d) setup 5, and (e, f) setup 9. The data in different clusters are plotted with different markers alternately, and the remaining true modal clusters are also marked with solid vertical lines.
